Answer: will be published.
The article will be published tomorrow.
Why this form?
Tomorrow refers to the future, so we use will.
Someone publishes the article; the article receives the action. That means we need the passive voice.
The Future Simple Passive follows this pattern:
will + be + past participle (V3)
Publish is a regular verb, so its past participle is published.
Putting the parts together: will + be + published.
Check:
- Active: Someone will publish the article tomorrow.
- Passive: The article will be published tomorrow.
Enter will be published in the answer box.
